Depression during pregnancy and after delivery: a repeated measurement study

Area of Science:

• Perinatal mental health
• Psychiatry
• Epidemiology

Background:

• Postpartum depression is a significant concern.
• Understanding depression prevalence across different maternal periods is crucial for targeted interventions.

Purpose of the Study:

• To compare the risk of depression during the early postpartum period (first four months) with pregnancy and the later postnatal year.
• To identify if the early postpartum phase presents a unique risk for depression.

Main Methods:

• A questionnaire study involving 416 postpartum women from two Norwegian municipalities.
• Utilized the Edinburgh Postnatal Depression Scale (EPDS) and Hopkins Symptom Check List-25 (SCL-25) to measure depression.
• Over 50% of participants completed an additional questionnaire covering other time points.

Main Results:

• The point prevalence of depression in the first four months postpartum was not significantly different compared to pregnancy or the rest of the postnatal year.
• This finding persisted after controlling for risk factors like life events, prior depression, and relationship quality.
• A non-significant trend suggested lower depression prevalence in early pregnancy and after eight months postpartum.

Conclusions:

• The early postpartum period (first four months) does not appear to have a higher prevalence of depression compared to other pregnancy and postnatal periods.
• Maternal mental health risk for depression may be more evenly distributed across the perinatal continuum than previously assumed.
